Orthotopic meningioma rat model exhibits morphological and immunohistochemical congruency and epigenetic concordance with benign primary patient-derived tumors.

Meningiomas are the most common primary central nervous system tumor. Clinical trials have failed to support effective medical treatments, despite initially promising animal studies. A key issue could be that available experimental models fail to mimic the clinical situation.

CRIME-Q-a unifying tool for critical appraisal of methodological (technical) quality, quality of reporting and risk of bias in animal research.

Background: Systematic reviews within the field of animal research are becoming more common. However, in animal translational research, issues related to methodological quality and quality of reporting continue to arise, potentially leading to underestimation or overestimation of the effects of interventions or prevent studies from being replicated. The various tools and checklists available to ensure good-quality studies and proper reporting include both unique and/or overlapping items and/or simply lack necessary elements or are too situational to certain conditions or diseases.

The risk of venous thromboembolism in adult patients with diffuse glioma: a nationwide population-based study.

Background And Purpose: Venous thromboembolism (VTE) is a cause of increased morbidity and risk of death. Studies report VTE in up to 30% of glioma patients but the results vary. The VTE risk is relevant when evaluating prophylaxis to avoid unnecessary bleeding or overdiagnosis.

Utilizing retinal arteriole/venule ratio to estimate intracranial pressure.

Purpose: Intracranial pressure (ICP) control is important to avoid secondary brain injury in patients with intracranial pathologies. Current methods for measuring ICP are invasive and carry risks of infection and hemorrhage. Previously we found correlation between ICP and the arteriole-venous ratio (A/V ratio) of retinal vessels in an outpatient setting.
